I personally couldn't take the time to do the creating part, but my son has spent hundreds of hours on Minecraft. He watched the video and is convinced he could make the best game ever. once this gets out to people, it will explode!

Same for me, my son 7 year old spends tons of time on minecraft.  I showed him the spark video and his eyes opened so wide I thought his head would split.  He cannot wait to get his hands on it and make games for himself and his friends.  If you look at the montage video that shows all the games MS people have made its pretty impressive the scope.  I am very interested to see what the community can do with this tool.  I know my older son spent a lot of time with little big planet making his very crappy games but he had so much joy in doing it.

My son just turned fifteen, but he still seems to fall back to Minecraft for many hours each week with a group of his friends.  He had a number of his friends that were thinking of going PS4, but after he convinced them to check this out, they have been convinced to stick with XBOne.

Amasing!

but im not so creative, but will download the tops and play hardly.
I dont like windows 8, i got sony and nintendo consoles, and i have ever turned the face to MS, but now i changed my mind.
next gen chosen.
Is the One.

Imagine someone with a game design degree using that program to demonstrate skills for some random games company when searching for a job. Main problem for many people whom just get out of college is that games companies usually looks for a proven track record, thus getting a job can be quite the challenge. With this you can quickly demonstrate your skills.

Imagine you creating a kickass game and uploading it to the Spark community and sell it for a buck. Other players can rate your game and top rated games will enter the top 10 within the community. Thus you can make a few buck being a top notch creator within the community. Of course, this could only work if the game sells like Minecraft. But the potential seems to be there.

Now I don't feel so bad for getting stuck with windows 8 on my powerful new laptop. This looks like fun to create some stuff with. Though I wonder if it will be like LBP, millions of levels, 1% of them really worth your time.
Anyway looks perfect for playing with my kids, 4 1/2 is old enough to learn how to make games :)

You know, that's how I feel with this. I don't want to get my hopes up, as I've never programmed anything far more interesting than your average thing with RPG Maker 2001, but I surely want to try and do something amazing.

Even if only one person likes it, I'd felt like I've accomplished something!

What I'm seeing is that there's no "control" or "censor" over someone's creation. While I am cool with this, we might be seeing some "questionable" content to download over the years, just as what happened with LBP.

That could be bad, especially with free control over character movements, gestures and voice. I never ran into questionable content with LBP, just tons of thophy levels and unfinished doodles from people. It took me a while too to get the hang of that editor but I didn't publish every little test level as seems most people do. Anyway if it is a success I'm sure external websites will pop up highlighting the best ones.

yeah i'm very interested in this but not for my own creativity but to see what ten-thousands of other gamers will create. i found the self-made maps you could play in far cry instincts already pretty fun and that was with a very limited editor.
